METAL-FRAME oonsr'iauorion. I

To all whom it may concern Be it known that I, CHARLES O. WHITNELL, a citizen of the United States, and a resident of Des Moines, in the county of Polk and State of Iowa have invented a certain new and useful Metal-Frame Construction, of which the following is a specification.

The object of my invention is to provide a simple and inexpensive metal frame construction designed to greatly lengthen the life of window frames and similar devices.

More particularly it is my object to provide in a frame construction used for windows and the like, particularly those used on a slanting roof, whereby water will be prevented from standing on the frame, thereby permitting the frame to dry quickly and avoid rusting.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a top or plan view of a frame construction embodying my invention.

Fig. 2 shows a sectional view taken on the line 2-2 of Fig. 1; and

Fig. 8 shows a vertical sectional View taken on the line 3-8 of Fig. 2.

My frame construction can be used for a great variety of purposes, as, for instance,

for a metal frame around a chimney or the like, but I have shown the construction embodied in a frame for a window of the type having a hinged glass supporting member and adapted to be used on a slanting roof, as for instance, in hog houses or the like.

n the accompanying drawings 1 have shown a window frame having the flashing comprising the side members 10 and the top member 11.

Extending upwardly at right angles from the inner edge of the flashing members is an upright window frame member 12. In the form of the device here shown the glass holding frame 13 is pivoted at 14' to the upper frame member 12.

It will be seen that the members 11 and Specification of Letters Patent.

12 are at the top of the frame when the de- It is found that after the installation of such frames it frequently occurs that there is a low place in the channel in which water collects and stands. Such a low place may be caused by a blow from a hammer or in various other ways. Wherever such a low place exists there is likely to be an accumulation of water which ultimately results in rusting the frame and causing a leak.

I have provided means for avoiding such an accumulation of water, by providing an upwardly extending rib 15 at the bottom of the channel formed between the member 12 and the member 11, which rib is illustrated in Figs. 1, 2 and 3 I have experimented for a long time in an effort to find some way to prevent the accumulation ofwater above referred to, but

have never been able to find a practical construction for forming a rib of the kind herein mentioned. It is very difiicult to form such a rib at the bottom of a sheet metal channel where the channel is formed by two portions of sheet metal bent, for instance, at right angles to each other.

Ihave at last succeeded in finding a practical way to make such a rib, and find that the rib works very efiiciently in preventing the accumulation of water at the top of the frame, and therefore greatly lengthens the life of the frame.

It will be noted that the rib 15 is highest at its central portion and gradually depressed toward its ends, so as to cause. water to run off at the sides of the frame.

. It is my intention to cover by my claims any kind of frame or any use to which the frame may be put which would be reasonably included within their scope. The device is, of course, particularly adapted to be used in connection with sheet metal frames.

1 claim as my invention:

1. In a sheet metal window framey-a substantially flat flashing, having. at its inner,

edge a frame member bent to stand at rightangles withv relation to the flashing, said flashing and frame member having an upwardly inclined rib between their ends along their line of junction, said rib being tapered from its central portion toward its ends.

2. In a sheet metal WlIlClOW frame; a substantially fiat flashing, having at its imier- Wardly inclined rib between their ends along their line of junction, said rib being tapered from its central portion toward its ends, and being formed partly in said flashing and aartly in said frame members.
